Registering temporary workers? Don't forget the legislation on temp agency work and temporary employment

Registering temporary workers takes more than handing over a contract. The laws and regulations on temp agency work in Belgium are strict and leave little room for error. From the right registration rules to the mandatory Dimona (immediate employment declaration): every detail matters if each period of employment is to run correctly.

At Recruit, we know how much it matters to get every step legally right when you take on temporary staff. The rules for temp workers are clearly set out in law and monitored by the FPS Employment, which means any mistake can have consequences.

With the right digital support, you handle your temp workers quickly, transparently and by the rules, without extra administrative obligations or the risk of fines. That keeps your organisation compliant, efficient and ready for every defined period when you need temporary reinforcement.

Meeting temp work and employment law

The legal framework for temp agency work in Belgium is strict and clearly set out in law. Every employment contract must be drawn up correctly and signed on time. If you register temporary workers, three essential rules keep the employment compliant.

#1 Choose the right employment contract

When you use temp agency work or another form of temporary work, the contract must always state a clear end date or a defined period. That reason might be a replacement, a temporary increase in workload or a specific project. If that description is missing, the worker can legally be treated as permanent staff, or even as a permanent employee, with all the consequences that brings.

#2 Equal working conditions for every temp worker

Every temp worker is entitled to the same pay and working conditions as colleagues doing full-time or part-time work in the same role. That means equal pay, equal benefits and equal treatment within the Joint Committee. This rule applies to short assignments as much as to a longer temp assignment.

#3 Sign the temp contract on time

An employment contract for temp agency work must always be signed before the work starts. If it isn't, the worker can automatically be regarded as permanently employed by the company.

With the right digital solution, these specific conditions are applied, checked and stored automatically. That way you avoid mistakes, stay in line with the FPS Employment, and every temp worker's placement runs fully in line with Belgian law.

Dimona declaration: avoid fines of up to €6,000

Every temporary worker or agency worker must be declared to the NSSO through Dimona before their work begins. This mandatory electronic notification confirms that the person is officially employed within your organisation. An incorrect or late declaration can lead to heavy penalties, up to €6,000 per staff member.

A correct Dimona is essential, because:

• No Dimona = no insurance in the event of an occupational accident
• No Dimona = a higher risk of inspection by the FPS Employment or the Flemish authorities
• No Dimona = requalification as undeclared work

Forgetting a Dimona or wrongly entering a fixed-term employment contract can also have consequences. The worker may then be regarded as permanently employed, which leads to extra social security contributions, a mandatory notice period, or corrections for back pay and benefits such as meal vouchers or annual leave.

Always correct, automatic and on time

With Recruit, that's nothing to worry about. Our platform makes sure every placement under temp agency work is declared automatically and without errors. Whether it's a single assignment, day contracts or successive day contracts for temp agency work, every work performance is registered and checked on time under the specific rules of the Act of 24 July 1987.

That keeps your administration in order at all times, fully compliant with the FPS Employment's rules and with no risk of mistakes. You save time, avoid fines and keep your legal employer obligations under control, while every worker enjoys the same protection and the same conditions as permanent staff.

With an automated Dimona through Recruit, every registration is correct, transparent and legally watertight, so you can keep growing with peace of mind, even during busy periods.

Foreign workers via temp agency work: mind the permits

Employing someone from abroad in Belgium means following a specific set of rules, to the letter. This matters especially in temp agency work, where people are often brought in for short, project-based assignments, so you need to check up front that the right permit is in place.

The right documents

For non-EU workers (except nationals of the EFTA countries), extra authorisations are mandatory, such as:

• a type B work permit, or
• a combined Single Permit (covering both residence and work).

Without these documents, temp agency work is not possible, and the worker may not be made available to your organisation. Forget the permit and you risk heavy fines, liability as the legal employer, and even a suspended status for your company if you are inspected.

The consequences of mistakes

A missing permit can lead to the employment being stopped, recovery of the gross salary already paid, and loss of the right to unemployment benefits for the worker concerned. On top of that, the authorities can temporarily ban cooperation with several temp workers or impose administrative penalties.

Failing to respect the weekly working time or exceeding the maximum duration of an assignment can also cause problems. With temp contracts or temporary appointments in particular, every employment contract must match the permit conditions exactly.

How Recruit helps

With Recruit, every registration is fully compliant. Our software automatically checks whether a permit is required and which type. So you know straight away whether the worker can legally start, how many hours per week are allowed, and whether the cooperation fits within the applicable legislation.

This automatic check not only prevents mistakes during hiring, it also makes sure every scenario where the parties end the contract is handled correctly in legal terms. That keeps your organisation protected, even in cases of work for economic reasons, a strike or lock-out, or a lack of work due to economic circumstances.

With a proactive control system, you stay in order at all times, with no risk of fines or interruptions to the placement service.
